Bonjour,
Réponse:
Yes I think that it's important to commemorate the first world war. We need to know what happens, to act rights and not doing the same mistakes. There's a lot of ways to commemorate it. We can for example put flowers in the grave of german or french people who died during this war or clean it. In my view, we need to preserve this collective memory of the two countries by showing that now we are peaceful and that we don't want a war anymore.
